Description

When comparing QGeoCoordinates with latitude +-90 and varying longitude then the equal operator returns true although the longitude values differ. The problem can be reproduced with this code:

#include <QDebug>
#include <QGeoCoordinate>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
    QGeoCoordinate coord(90, 180);
    for (int i=0; i<50; i++)
    {
        auto coord2 = QGeoCoordinate(coord.latitude(), coord.longitude()-i*0.1);
        qDebug() << coord << coord2 << (coord == coord2);
    }
    return 0;
}

which outputs:

QGeoCoordinate(90, 180) QGeoCoordinate(90, 180) true
QGeoCoordinate(90, 180) QGeoCoordinate(90, 179.9) true
QGeoCoordinate(90, 180) QGeoCoordinate(90, 179.8) true
